Case Study: How We Made Our Client 100k in 2025 Through Email Marketing
Let’s talk about email marketing. It's the channel everyone loves to ignore or spread rumors about it "being dead" until...it starts making real money.
In 2025, we helped one of our clients bring in $100K+ through email marketing alone (and note that we started working with them in September), and it didn’t happen by chance.
This case study walks you through the strategy, the systems we put in place, and the small tweaks that led to major revenue.
Background on The Client
Before we dive into the strategy, here's a quick overview of this client to add more content. Weddell Water’s mission is simple yet powerful: make cleaner, healthier showers accessible to everyone. Their filters improve skin hydration and scalp health while removing harmful chemicals, a true self-care essential backed by science.
So, their emails needed to reflect the quality of their product. They needed a strategic, story-driven email system that could educate their audience, build trust, and drive repeat sales.
Weddell Water came on board under our Customized Email Package, which included:
The Weddell Refresh: a monthly newsletter focused on lifestyle, clean beauty, and self-care content
The Deep Dive: a quarterly edition highlighting impact stories, partnerships, and community features
Four Core Email Flows:
Welcome Series
Post-Purchase & Retention Flow
Conversion Campaigns
Re-Engagement Campaign
The Email Marketing Strategy
Our email marketing strategy was built to support the full buyer’s journey and the customer experience, not just push promotions.
First, we focused on creating automated flows that welcomed new subscribers, educated them on the brand, and nurtured them toward conversion over time. These flows worked behind the scenes to keep subscribers engaged even when campaigns weren’t being sent, ensuring no one fell through the cracks after joining the list. Warming up your audience on any marketing channel is key. Each flow was designed to meet subscribers where they were, guiding them from awareness to action in a way that felt natural.
Alongside flows, we executed consistent, value-driven email campaigns to keep the list active and engaged. A key part of this strategy was optimized subject lines and thoughtful segmentation, meaning sending the right message to the right people at the right time. Rather than emailing the full list, we segmented subscribers based on engagement and behavior, which helped increase open rates and improve click-throughs. This approach kept subscribers sticking around longer and continuing to foster a community and loyal purchasers.
When we create email strategies for clients, we really lean into the importance of having both email flows and regular campaigns to drive sales and community, because these two work together to not only get subscribers on the list, but to keep them there. You'll see how this clicked in the next section.
The Results
In 2025, this email marketing strategy generated $106,453.01 in total sales. Campaigns accounted for $43,709.49 in revenue, while automated flows drove $62,743.52, again highlighting the importance of both. Our most successful flows are the Welcome series and the abandoned cart flow.
The email list grew by 7,896 subscribers throughout the year, with strong engagement across both campaigns and flows. Campaigns averaged a 42.04% open rate and 1.72% click rate, while flows outperformed with a 43.57% open rate and 3.46% click rate. This proves that segmentation, strong subject lines, and a flow-first strategy lead to powerful engagement and revenue growth.
In conclusion, when done the right way, email marketing is one of the highest-ROI tools in your marketing stack. In 2025, we partnered with a client to refine their email strategy and turn their list into a consistent revenue driver. And in 2026, that revenue could be yours, too.
